Sand Making Operation Regulations
  • 1. Check whether the door of the vortex chamber is closed before driving the sand making machine to prevent the material from rushing out of the vortex chamber.
  • 2. Check the rotation direction of the sand making machine impeller, and look from the direction of the material inlet. The impeller should be rotated counterclockwise, otherwise the motor wiring should be adjusted.
  • 3, the start sequence of sand making machine and conveying equipment is: discharging → sand making machine → feeding sand making machine must be started with no load, and the direction of feeding of the sand making machine after normal operation. The shutdown sequence is the reverse of the boot sequence.
  • 4. The feeding granules of the sand making machine are strictly in accordance with the stipulated requirements, and it is forbidden to enter the sand making machine larger than the stipulated materials. Otherwise, the imbalance of the impeller and excessive wear of the impeller will be caused, and the impeller passage and the center feeding pipe will be caused to be blocked by the base. The sand machine did not work properly, and it was found that large pieces of material should be removed in time.
  • 5. When the sand making machine discharge equipment stops, feed should be stopped in time. Otherwise, the impeller will be crushed and the motor burned.
  • 6. The feeding of the sand making machine strives to be continuous and uniform.
  • 7. During the operation of the sand making machine, there shall be no severe vibration and abnormal noise. Otherwise, it shall be stopped and checked.
  • 8, the lubrication of the machine

Lubrication is a dry-oil lubrication method. It uses Mobil's premium grease, 1/2 to 2/3 of the bearing cavity, and every time the sand making machine works, it adds grease, and after working for a certain number of hours, Open the main bearing to clean the main bearing and replace the bearing if necessary.

Maintenance and safety
  • 1. Regularly stop and open the observation door to observe the internal abrasion of the impact sand making machine. The wear degree of the center feeding pipe, conical cap, impeller upper and lower runner lining plate, circumferential protection plate and wear-resistant block should be replaced after wear. When repairing, replacing the wear-resistant block should be replaced at the same time to ensure that the wear-resistant block has the same weight. It is forbidden to open the observation door to observe the internal working conditions during the operation of the sand making machine to avoid danger. It was found that the impeller body was worn out and promptly replaced by the manufacturer. In particular, it is strictly forbidden to create impellers without permission from the manufacturer.
  • 2. The tightening force of the transmission triangle tape should be adjusted properly to ensure uniform force of the triangular tape. When the dual motor is driven, the triangle tapes on both sides should be grouped and matched, and the length of each group should be as uniform as possible. Should be adjusted so that the current difference between the two motors does not exceed 15A.
  • 3, sand making machine uses Mobil vehicle grease special grade or 3# lithium grease, add proper amount of grease every 400 hours of work, work 2,000 hours to open the spindle assembly to clean the bearing, generally work 7200 hours, replace the new bearing.

The upper bearing of the main shaft assembly is a floating end, and the lower end bearing is a fixed end. After the assembly, pulling the pulley by hand should be flexible. In the operation of the sand making machine, due to the high-speed equipment, special attention should be paid to safe production. The personnel concerned should be away from the equipment. If it is necessary to repair the equipment, it should be carried out after shutdown. There is a problem suggest that you ask a professional maintenance staff to solve, without the manufacturer's permission is strictly prohibited from dismantling the core components.

The 5X new sand making machine is the main equipment used exclusively for the production of construction sand. The entire sand making production line also mainly includes feeders, sand making machines, vibrating screens, sand washing machines and conveyors.
